I'd be very curious why you consider it "not worth it". Honest question, not trying to be combative.
I've watched several YT videos where people have given a "now that I've had it a while, let me give you my opinion", and "what I might have done differently" type of reports, and the only time anyone's complained about the smaller ones (that is, wished they had a bigger one) it's simply been a matter of the physical size of the workpiece.
I'm severely limited in both physical space and funds, and the vast majority of my workpieces will be both aluminum and well within the work envelope of the 440.
I'd love to have the 1100, but even if I just got the 440, at least one, if not two machines are going to have to go away, first. I literally have zero room.
